Drain Plug Torque Spec?

[markseven]

Is there a specific torque spec for the engine oil drain plug? I searched the board with no luck, no luck with the Bently, either...

TIGHT is the torque spec that I use.

But seriously if you have a good washer behind the plug you should be able to "feel" the proper tightness. Its very difficult to overtighten it with a standard wrench.

Yup, pretty much what I have been doing. I just picked up a torque wrench from **gasp** Harbor Fright for **gasp** $14.95 and wanted to try it out.

Thanks man! :D I don't know how I missed that

I only concern myself with the torque when it comes to installing head bolts or other internal engine parts. I find that if I torque most other things to the required specs, its never really tight enough.

This is OK on some oil pans, but weak aluminum pans, like newer VW's, will wear out and strip VERY quickly with even slight over tightening - so don't make it a habit. When I worked at a lube shop we had charts for torque specs on drain plugs, and you would be surprised how little or high some were. Anything from 15 lbs/ft to 45 lbs/ft IIRC. Always make sure you use a brand new OEM style gasket (whether it's fiber, rubber, copper, or aluminum). Always.

turn it as hard as you possibly can to ensure proper tightness - i strongly encourage the use of an air wrench/impact gun.

Ted is right, a breaker bar on the end of your wrench might be a good idea, too.

But seriously, just good and tight is enough for the drain plug.

I swear that's what Crevier used on my 540 when they performed Inspection I & II services.
